Sheepish B cells: evidence for antigen-independent antibody diversification in humans and mice

J Exp Med. 2008 Jun 9;205(6):1251-4. doi: 10.1084/jem.20081057. Epub 2008 Jun 2.

Abstract

Antibody diversity is first generated by rearrangement of immunoglobulin (Ig) genes during B cell development in the bone marrow, and later by antigen-driven diversification in germinal centers (GCs). New data in humans and mice now identify specific B cell populations that may have undergone antigen-independent hypermutation outside GCs.
